These conventional sorters have a large number of paper trays with shelves (bins) arranged in multiple stages on the top of the water, and each time paper is introduced, these shelves are moved in the vertical direction to sequentially pick up paper and arrange the pages. The inventor filed a patent application in 1982.
There is a method that uses belts to sandwich sheets of paper and circularly transport them to align the pages, as previously proposed in No. 9898.

However, according to these sorters, for example, in the case of the former, there are n points such as a large-scale device configuration and a difficulty in achieving a 91-column size, and in the case of the latter, the number of copies to be sorted is It has n points such as being limited by the length and not being suitable for aligning pages of a large number of copies, and that it is difficult to align the edges of the paper due to static electricity generated on the paper by circulating WI feeding.

Therefore, the present invention converts the n point to i! It was created to eliminate IV, and its gist is (It!l board has a large number of m plates at regular intervals in the circumferential direction, and each shelf is The plates are arranged so that they are inclined and have a spiral cross-section, and a paper stopper is provided on the lower surface of the rear end edge of each shelf board, and the paper stopper is installed on the extension of the rear end of each shelf board.
This is due to the fact that paper holding means is provided up to the forming section.

An embodiment of the present invention will be described below with reference to the drawings.

In the figure, reference numeral 1 denotes a side plate that is entirely disc-shaped.

A shelf board 2 is arranged on the peripheral edge of this side plate 1. The shelf board 2 is bent into an arc shape with the same curvature as the peripheral edge of the side board 1. In the illustrated example, the shelf board 2 is disposed at a height extending into 12 equal parts of the I'PiI edge of the side board 1. Moreover, each shelf board 2 is arranged so as to be inclined with respect to the periphery formed by the tip edge of each shoe 2, that is, the periphery of the side plate 1, and to have a spiral cross section.

A paper stopper 3 is provided on the bottom surface of the far edge of each shelf board 2.

In addition, a clamp release plate 14 is arranged on the machine frame 13 facing the side plate 1, parallel to the direction in which the drum 12 is applied, and positioned inward from the rotational diameter of the engagement bin 7 by the pushing length. When the drum 12 is at a specific position angle (that is, the position angle at which the engaging bin 7 is engaged with the gripping release plate 14), the gripper plate 4 in the shelf 11 is released from pressing against the shelf board 2, and the paper tray is opened. Insertion status or paper l! Set to Y discharge state. Further, when the gripper plate 4 is at a position other than the specified angle, it is pressed toward the shelf board 11 by the torsion coil spring 9, so that the paper can be firmly held within the shelf 11.

In addition, a plurality of notches 16 are formed in the shelf board 2 along the circumferential direction of the bin drum 12, and a paper branching mechanism 3, which will be described later, is provided.
Even if the tip of the shelf gate 35 is arranged so as to be located inside the shelf 11, the rotation of the bin drum 12 is not hindered.

The binding drum 12 of the present invention is attached to a collating machine Δ, a page alignment device (not shown), etc. by mounting it on a frame plate 13Δ of a machine frame 13. Then, the shelf 11 with the gripper plate 4 in the gripping release state
A paper guide plate 17 is disposed around the periphery of the bin drum 12 except for the openings of the bin drum 12 to cover the openings of each shelf 11 of the bin drum 12, and protects and smoothly guides the paper during page alignment. I'm trying.

In use, the hint ram rotation control plate 18, which has the same number of notches 18A as the number 1811 of the bind drum 12, formed on the periphery at equal intervals, is fixed to one rotary shaft disposed in the center of the side plate 1, and an electromagnetic clutch brake is attached. 20. The rotation VJ shaft 19 is connected to a 1/11A drive motor 23 via a belt transmission means 21 and a reduction gear train 22.

Further, a paper branching mechanism 30 is disposed at the opening of the shelf 11 at the position where the gripper plate 4 is released.

The branch 1 structure 30 is connected to the conveyance roller 31, etc.

The introductory guide h34, which guides a group of sheets to the binding (imaginary 50), is located below the opposing contact part, usually guides the sheets to each tI4+11, and swings only when an unavoidable sheet is conveyed. and eject the paper to paper output roller 6.
Shelves 1 to 35 guide the paper to the shelves 1 to 35, and when paper is introduced into the shelf 1111, it works together with the shelf gate 35 to reliably guide the paper. C, which discharges the paper group, swings upward to the shelf 1 of paper nY.
1 and a presser gate 36 to ensure that there is no hindrance to the discharge from 1.

In the figure, reference numeral 40 denotes an introduction path that guides paper sent from a copying machine or the like to the branching mechanism 30, and is swingably disposed by a conveyor belt 41 and a retainer 42 or the like above the conveyor belt 41. The ball 43 rotates in opposing contact with the belt 41.

Further, reference numeral 50 in the figure denotes a binding mechanism disposed above the introduction path 40, which binds the sheets discharged from the branching mechanism 30 and opens binding holes, and discharges the sheet group receiver into the tray 51. Its configuration includes a conveyor belt 52 for a sheet group and a conveyor belt 1 for conveying a group of sheets.
-52's inlet pulley 53 press-contacts the conveyor's feed force port 54, a stapler 55 and a perforator 56 arranged at the rear of the conveyor bells 1 to 52, and a lever for operating these stapler 55 and perforator 56. a discharge pressure roller 6 with an actuation cam 57 and an actuation rod 58, a discharge roller 60 and a branch gate 59;
Consists of 1. Reference numeral 62 in the figure represents a paper ejecting roller that ejects the paper to the outside of the gate frame 13 when a paper of a size other than the specified size is introduced, or when the same copy paper from 11 or more shelves is introduced.

Next, we will explain how to take in paper, align pages, and eject paper.

The copied sheet is introduced into the so-called 11 in which the gripper plate 4 is in the released state through the introduction path/IO1 branch 30. The position of the introduced paper is confirmed by a counter sent to the paper confirmation sensor 37 provided at the branch fam 30, and after passing through the paper confirmation sensor 37 for a certain period of time, is the length of shelf 11H [
In Figure 2, the block rotates in the counterclockwise direction, and the next 611
111 to introduce paper. In addition, Bintrum 1
2, the reduction ratio of the reduction gear train 22, etc. is determined so that the circumferential speed at the innermost part of the town 11 where the stopper 3 is located is the same as the paper conveyance speed. Paper jams are prevented by preventing paper from bending during group ejection.

By sequentially introducing paper in this way, each fence 11
Inside, the copied sheets are stacked in page order (pages are aligned). When paper is introduced, the week gate 35 presses the previously introduced paper 8Y from above, and the next paper is placed in the shelf 11. Secure introduction space and ensure page alignment.

Further, the group of sheets in each shelf '11 whose pages have been aligned are discharged to the branch 1 structure 30 by rotating the drive motor 23 in the reverse direction. still,
At the time of ejection, the tips of Shelf Goo 1 to 35 scoop up the group of sheets in ll1l111 from above, thereby facilitating reliable ejection.

(the present invention), since the conventional horizontal paper tray is configured with multiple shelves (two shelves), these multi-circular paper trays require extensive work by moving the shelves in the vertical direction. The configuration is simple and does not require any special equipment configuration.
can be provided to In addition, when a pair of annular bells h are placed in opposing contact to sandwich the paper and align the pages, static electricity is generated by circulating the paper, and this static electricity makes it difficult to introduce the paper and align the edges of the paper. However, in the apparatus of the present invention, almost the entire sheet of paper can be held within the shelf 11, thereby suppressing the generation of static electricity as much as possible. Therefore, various problems caused by static electricity on the paper, such as difficulty in introducing the paper and difficulty in aligning the edges of the paper, can be eliminated.

In addition, a large number of shelf boards 2 are placed on the side plate 1 at regular intervals in the circumferential direction, and the edges formed by the tip edges of each shelf board 2 are arranged so that each shelf board 2 is inclined and has a spiral cross section. As a result, the six shelves 11 can be formed on the circumferential surface of the cylindrical body at regular intervals in the circumferential direction, and the shelves 11 can be arranged efficiently, making it easy to convert the device into a single unit. Moreover, since the shelves 11 are arranged on the same circumference, even when a large number of papers are held in each shelf 11, a large amount of work is required to move the shelves, unlike when the shelves are arranged in multiple stages. There is no need for such movement, and the effort required to move it is extremely small, making it possible to downsize the drive device and save power.

Furthermore, the introduction of paper into the 1111 and the ejection of a group of papers can be achieved by the simple operation of rotating the drum, and there is no need for a large-scale device configuration or complicated control as in the prior art.

In addition, six shelves 11 are arranged at an angle with respect to the periphery of the bin drum 12, and when discharging or unloading a group of sheets, the bin drum 12 is reversed and the shelves 1-35 are placed on the shelf 11.
By being located inside, the group of sheets can be easily ejected.

In addition, by bending the shelf board 2 into an arc shape and arranging it so that the bulge extends outward, the allowable length of paper that can be introduced into the shelf 11 can be increased compared to a flat shelf board. In addition, the shelves 11 can be disposed at high density on the periphery, making the device even more compact.

As explained above, according to the present invention, a shelf for a collating machine such as a copier can be provided with a simple and compact structure, and furthermore, it is easy to introduce paper and eject a group of papers, and it is possible to use an additional device. The device configuration can be simplified, and furthermore, an excellent multi-effect rack can be obtained, such as a small work rack for introducing paper and discharging sheets of paper, enabling efficient operation. .
